Not anymore.

Please state the language next time. I guess it's Javascript.

I think the problem is with n = 0, the reference solution expects 0 and your solutions returns 1, but this edge case is tested only randomly, and the description should give explanations about it. I think nth fibonacci doesn't make sense with n < 1, so there's something unclear here (the description says the sequence starts with 0, 1, some variations assume it's 1, 1; however the description is incorrect since in sample tests for n = 1, the expected answer is 1). Some clarifications are needed (this should be raised as an issue IMO).

Please use spoiler flag next time.
